Cats on Canvas

The Skinner auction house in Park Plaza will hold the nation's first-ever all-cat art auction on September 20, featuring the world's largest antique cat painting, which could fetch more than $500,000.

Cat lovers can bid on more than 200 pieces of paraphernalia, including sculptures, jewelry, clothing, furniture, and My Wife's Lovers, a 19th-century painting by artist Carl Kahler of 42 cats doing what cats do: nothing.

“We didn't have to invent the wheel of cat paintings,” says spokeswoman Colleene Fesko. “It was a favorite subject of the 19th century.”

Some proceeds will go to the Massachusetts Society for the Prevention of Cruelty to Animals.
